I have a 4g63 motor with 185,654miles and I spray... (of course the tranny is broken) but none the less... 4g63 is a STRONG motor... Im Biased... I have 2 of them... both are broken...hahaha.... you'll have that with 10 years of 8K rpms... SR20 is a Badass... no doubt... If you are going to post this kind of question.. break it down... different classes... cuz Honda has a few motors that arent bad either... MY vote is for 4g63... AKA bullet proof block... STOUT lil bastard.
